that's a very good point. I took out my glass on my 65 for small scratches left by the windshield wiper. It didn't exactly fit in the dumpster in one piece
So I did that with the thought that when I drive the car I will see a brand new windshield and dash and fool the senses into thinking the whole car is brand new. The rear glass has a few small scratches from the bone head who sanded it down but it won't be in front of my face so it stays.
